Application filed April 23,

The invention relates to window shutters and has for its object to provide a device of this character formed-from a plurality of slats adapted to be rolled upon aroller within the upper end'of a window frame for s orage purposes. The shutter is preferably "posed outsine hie window to protect the window from damage, incident to storms and also to exclude cold and heat.

A further object is to slidably mount the sides of the slat shutter in fixed upper chan nels on the inner faces of the sides of the window frame, and to hingedly connect lowcr channel sections to the first mentionec channels thereby allowing the lower portion of the shutter to be moved outwardly for allowing free circulation of air through the lower part of the window.

A. further object is to provide the slats forming the upper portion of the shutter with flexible connections. whereby the upper portion of the shutter will roll on the roller, and the lower portion of the shutter with connections between the slats, which con? nections are constructed in such a manner whereby air may pass between the slats or the slats may be moved into engagement with each other for excluding air.

A further object is to provide cable means whereby the roller may be rotated from within the building. 7

With the above and other objects in view the invention resides in the combination and arran ement of parts as hereinafter set forth shown in the drawings, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings Figure 1 is a front elevation of a window frame, showing the shutter applied thereto.

Figure 2 is a vertical transverse sectional view through the window frame and the shutter taken on line 22 of Figure 1.

Figure 3 is a detail perspective view showing adjacent slats in section and the loose connection therebetween.

Figure 4 is a detail perspective View of a portion of one of the'guide channels showing the hinged connection therein.

Figure 5 is a horizontal sectional view through the lower portion of the window frame and shutter.

Referring to the drawings, the numeral 1 designates a conventional form of window frame, and 2 the slat shutter carried thereby at the outerside of the window sash. 3. it has been found that the glasses f within the sash are. often damaged in storms, par ticularly hail storms and to obviate this difficulty, well as regulate the amount of air passing through the window the slut shutter is primarily designed. Shutters as atpresent used are usually of the hinged type which are hard to manipulate particularly to close in a heavy wind. However by providing the slat shutter 2. which is vertically movable and guidable in vertically disposed channels 5 fixedly carried by the inner side of the frame 1 the shuttermay be easily raised and lowered, even in an extremely heavy wind. The shutter 2 has its slats 7, which form its upper portion substantially in engagement with each other and connected together by flexible bands 8, which bands extend upwardly, and onto the roller 9 disposed in the upper portion of the window frame 1. It will be seen that when the roller 9 is rotated in the direction of the arrow a, the upper portion of the shutter will be rolled onto the roller, and will be out of sight. lowever when the upper portion of the shutter is wound around the roller 9, the lower portion of the shutter,

of links 11, which links have slot connections 12 with transversely disposed pins 13, which extend through the slats, therefore it will be seen that when the slats are suspended spaces will be formed between the slats incident to the weight thereof thereby allowing a limited amount of air to pass through the lower portion of theshutter for ventilat ing purposes. Howevenwhen the shutter is lowered to a position where the slats 10 will rest against each other, it will be seen that the spaces 14 between the slats will be closed, consequently light, heat or air will be exeluded from pasing through the window The links 11 are formed from metal and extend into enlarged slots 15 in the slats 10. therefore it will be seen that the slats may have a freedom of movement longitudinally as the shutter moves upwardly and downwardly in the channels 5, thereby preventing sticking or ammlng of the slats.

The lower sections of the channels 5 are hingedly connected at to the upper with right angled portions 19 adapted to be received in sockets 20 for holding the lower portion oi the shutter in outer position.

To raise and lower the shutter, an endless cable 21 is provided, which cable has its portion 22 disposed to the inside of the window frame where it can be easily reached and manipulated by a person within the building. Cable 21 extends upwardly over the pulley 23, thence through the side of the window frame and upwardly over the pulley 2% carried by the roller 9. Cable 21 atter passing over the pulley 2% extends downwardly through the side of the window frame and under the pulley 25, therefore it will be seen that only the portion of the cable which is grasped by the operator during the manipulation of the device is exposed to view within the room.

From the above it will be seen that a window shutter is provided, which is formed from a plurality of slats and con per section, a lower section, said upper section and lower section being slidably mount ed in guides termed from channel members, said lower section having its slats linked together and maintained in the same plane, said gzj-uides having their lower ends hinged ly mounted and movable to angular positions with the guides, said upper sections being normally disposed in the upper-port ons of the guides, flexible connections between the slats of the upper section and the upper end of the lower section, a roller above the guides, said upper section'being rollable onto the roller and limited in its upward movement by the upper end of the lower section. c
